3D printing gets a big endorsement from HP CEO Meg Whitman

Above: Type A Machines makes a 3D printer that competes with MakerBot. Why buy a Type A instead? It is $900 cheaper, prints larger objects (up to 10x9x9 inches), and is more reliable, according to Elijah Post (pictured on the right), who creates documentation and does tech support for the company. He said the machine had been tested out with a 48-hour continuous print job and didn't stop once -- a rarity in the world of 3D printing, apparently. Side note: Type A's headquarters are on the top floor of TechShop San Francisco, a popular workshop for hackers and makers.
